Who brought religion into this thread? Why can't we have a rational debate for once?
Because the only 3 reasons anyone can possibly have to hate gays is that they're gross, god said cigarettes need to be viciously stabbed, lit on fire, and thrown into a bottomless pit, or gays cause disease.
And honestly, those 3 reasons are all godawful. Gays don't go around buttloving each other on peoples' front porches. Furthermore, fat people wearing bikini's are gross, no one bans that. Throw up is gross, but people don't go to jail for throwing up. On an even more relevant note, liking men is considered gross, but only men are bitched at for doing that. I mean seriously, that's loveism more than bigotry, and I for one hate beyond all hell loveism towards either love (though note: I never said I'm not a hypocrite).
As for "God says gays are bad"- Really? That's an even worse reason than "they're gross." There is separation of church and state for a reason (at least in the U.S., anyways); to prevent starfishs like you from banning people from doing things because a bunch of old people wrote stuff and said some celestial being made a bunch of rules and now we need to follow them. Furthermore, even if God does say "cigarettes are bad," so what? You aren't a cigarette so that doesn't affect you. Let them be gay together and let God deal with them in the afterlife. If you truly believe in God, take faith in knowing that God will smite their asses (no pun intended) once they die.
Oh, and that whole "gays cause disease" deal is absolute bullstuff. I'm not saying they didn't spread AIDS as I have heard rumors that it started with a gay flight attendant, what I'm saying is that it doesn't matter if gays spread the disease. It's here now and it affects everyone not just gay people. Heteroloveuals don't have some sort of magical immunity. Furthermore I bet if it was rumored to be a heteroloveual who started it no one would be all "man those heteroloveuals! What douchebags."
Come up with new points and stop repeating the same ones over and over again.
(Also, this is not directed at the OP. To me it seems like the OP just disagrees with the lifestyle that gays have.)
